does not provide any explanation what 'equal' or 'run' may mean. Maybe
add something like "where equality is assessed only based on the keys
and rules used to sort the output".
Thanks for the suggestion. Although that's a bit long for "sort --help",
I take the point that equality comparison could be mentioned and
installed the attached to try to make things clearer without adding so
much length.From 3324344820b6f3566ed659befe9bbfcf2b1f1298 Mon Sep 17 00:00:00 2001
